SWAGING TOOL.

Application filed February 10, 1923. Serial No. 618,215.

To aZZ whom t may concern.'

Be itv known that l, HAROLD W. Gore, a citizen of the United States ofAmerica, `residing at New York, in the county of New York' and State ofNew York, have invented certain new and useful Improvements in SwagingTools, of which the following is a full, clear, concise, and exa-ctdescription.

This invention relates to improvements in the method and means foradjusting certain operating parts of light machinery.,

More particularly itrefers to a measuring fixture and swaging tool foradjusting the operating members such as are used in the selectingmechanism of coordinate switches of the type disclosed in the Britishpatent to 1Western Electric Company, Limit-ed, No. 197,891, accepted May2-1, 1923.

In such mechanism it is necessary to adjust by a bending operation, arelatively great number of parts which are generally made of relativelythin sheet metal of such a width that they do not easily yield to aforce applied to bend them in that plane.

The object of this invention is the provision of a simple and eiici'entadjusting tool for adjusting the parts of mechanisms of the type towhich reference has been made.

A feature of the tool resides in the provision of a pair of special jawsattached to compound lever pliers by means of which indentures are madealong the edges of the part to be adjusted. Another feature .is theprovision of a stop attached on one of the jaws and adapted to assist inpositioning the swaging tool with respect to the part to be adjusted andto limit the extent of the indenture to be effected thereon.

A feature in the measuring fixture is the provision of a graduated indexwhich is common to a plurality of operating members and by means ofwhich -the adjustment of each of said operating members is easilyascertained.

Another feature in the measuring fixture is the provision of locatingmeans for the support of the operating members by means of which itsexact location relative to the index is readily secured.

The invention will be more readily understood by the followingdescription and by the claims appended thereto, reference being had tothe accompanying drawings in which Fig. 1 is a plan assembly View of theswag-V ing tool shown with its jaws opened and the stop overlapping thecams, Fig. 2 1s a front assem ly view of the swagmg tool showing va partto be swaged positioned between the cams, and Fig. 3 is a perspectiveand partial view of the fixture used in connection with he swaging toolshowing. a graduated index, a face plate supporting the same and aportion of a bar on which the lifting lingers are secured shown inadjusted position onthe plate.

The swaging tool shown in Fig 1 comprises an ordinary pair of compoundpliers designated by the reference character A. On the jaws 8 and 9 ofsaid pliers are securely attached a pair of swages 10 and 11. The stop14 is secured on the swage 10 by means of the screws 15 and 16 and itsfree end is adjusted to extend over the central portion of itscooperating swage 11. The stop 1&1 is provided to assist in positioningthe swaging tool on the part 35 to be adjusted and to limit thereon theyextent of the'indent-ure to be impressed, in order to bend the free endportion of said part toward its respective orientation point.

The measuring fixture contemplated for use in connection with the abovedescribed swaging tool is shown in Fig. 3 and comprises preferably anoblong apertured face plate 1li on one edge of which the graduated index.17 is secured by means of screws 18, etc. l

, .r, etc. made 4along the index 1T are adapted to indicate the paralleladjustment of lifting fingers 2l), 30, etc., when assembled on theoperating bar 2l). This bar 2O which in connection with the coordinateswitch is generally referred t-o as link bar, has a number of locatingholes drilled at intervals and which registerA with similarly spacedholes drilled along the opposite edge of the vfixture and in which thepins L8 are insertedfor the purpose of pi operly positioning the bar andlift ing` lingers thereon with reference to their respective marks onthe index 17. In addition to locating pins i223, etc., the bar Q0 isheld in adjusted position on the fixture plate 16 by means of a numberof screws 22, etc. 1n that adjusted position, if it is supposed that theoperating members have been correctly assembled on the bar, theirpointed end portions Q4, 24;', will be in juxtaposition with the pointededge 25 or' the common index 17 and their respective graduation marks,as shown by Fig. 3. Ift`,however, any one of the operating membersdeviates from its adjusted position for example, as indifated. by thedotted line at B, an indenture is impressed along' the edge of saidmember as shown at Q6 which has for result the bending of said part 35toward its adjustA ed position through ythe spreading of the instal inthat portion. H the end of the linger 24C registers with the edge 25 butnot with the index line L8, then a simple bending operating atrightangles to the plane of the linger W'illbring it into its properposi tion.

Vhat is claimed is:

l. A device for adjusting sheet metal strips comprising a pair ofpliers, a sWage attached to each jaw ot' said pliers tor spreading themetalalong one edge to cause its free end portion to bent toward apredetermined position, and means carried by one of said swages toassist in positioning said device.

2. A swaging' tool comprising a pair oi compound lever pliers, a swageattached to each jaw of said pliers, and means carried by one oisaidswagcs to assist in positioning said tool on the material to be swaged,preparatory to its adjustment by means of said sWages.

B. A sWa-ging tool comprising a pair oi. compound lever pliers, a swageattached to each jaw of said pliers, said swages being arranged withtheir top Cooperating edges direrging from a common apex, and meanscarried by one of said swagcs to assist in positioning` said vtool onthe material t'o be swaO'ed ire aratory to its ad'ustnient b*7 means ofsaid s rages, so that said. aocx will appeal' beyond the `limits et thematerial.

In Witness whereof, I hereunto .subscribe my naine this 5 day ofFebruary A. D.,

HAROLD VHEELER GOEE.
